Here’s how the data looks:
The concise summary is that there is virtually no difference in likelihood of testing positive based on mask wearing in the UK.
The underlying data provided in the survey shows how useless mask wearing is in greater detail, as they’ve helpfully provided a breakdown of the sample sizes and results in the different categories.
Of the 28,942 adults surveyed who “always” wore a mask, 7%, or 2,020 tested positive.
Of those who indicated masks were “not needed,” 3,962 out of 66,545 tested positive, which is 5.95%.
The “sometimes” category resulted in a 7.3% positive testing rate, 1,073 out of 14,671, and the “never” group had an identical 7.3% percentage.
Similarly, among children, 164 of the 2,643 in the “always” wore masks designation tested positive, a rate of 6.2%. The “sometimes” category had 125 positives out of 2,446, which is a rate of 5.1%.
Compared to the reference group, those that “always” wore masks, both school aged children and adults had nearly identical results.
For example, the group of children who “never” wore masks were just as likely to test positive as those who “always” wore masks.
Masks don’t work.
Similarly, adults who worked or attended school in settings where masks were “not needed” were less likely to test positive than those who “always” wore masks in those same settings.
Masks don’t work.
Those who only wore masks “sometimes” had no significant difference either way.
